The optimisation of modern energy systems

Over 90% of energy systems in Germany are not optimized or provide useful data for operators. GEMControl ensures cost-optimized, fully automatic, and transparent functioning of heat pumps and PV systems. It monitors, analyzes, and controls, resulting in higher performance coefficients, reduced and focussed technician time, optimized power flows, etc. GEMControl includes GEMBox (on-site hardware connected to all relevant devices), GEMNet (cloud-based telemetry), and GEMApp (mobile companion). It is manufacturer-independent and compatible with devices providing readout and control interfaces.
